The federal government uses Goods and Services Identification Number (GSIN) codes to identify generic product descriptions for its procurement activities. Coming in 2020, the United Nations Standard Products and Services Code (UNSPSC) will replace GSIN codes. There is no immediate impact to businesses or government buyers.

How do I use a GSIN?

Knowing your GSIN(s) is very important for finding procurement information on Buyandsell.gc.ca. Read the Get Started with GSINs page to find out how.

How does the GSIN work?

The GSIN structure includes a prefix, a core that is made up of two levels of hierarchy, and a suffix. The hierarchy in the core is made up of the Group (first level) and the Class (second level).

The structure between goods, services, and construction codes varies as follows:

  • Goods codes: are closely related to the United States Federal Supply Code / Product Service Code (FSC/PSC) classification system
  • Services codes: are closely related to the North American Free Trade Agreement (NAFTA) Common Classification System
  • Construction codes: are closely related to the United Nations Central Product Classification (CPC) Division 51, as adopted in NAFTA

The collection of codes for these three types of commodities was established in NAFTA, signed in December 1992.
